XP and ranks
XP is a score for being right, weighted by how hard the call was. Total XP puts you on a rank, and each rank carries a share of Backd's fee that accrues to your account.
XP
A right call earns max(1, round(10 ÷ the chance you got in at)). Yes at 58% earns 17 XP, at 50% earns 20, at 25% earns 40, and a 10% long shot that lands earns 100. Longer odds, more XP. It doesn't depend on the stake, so a $1 call and a $500 call earn the same.
| Backed at | XP if right | XP if wrong |
|---|---|---|
| 90% | 11 | 0 |
| 75% | 13 | 0 |
| 50% | 20 | 0 |
| 25% | 40 | 0 |
| 10% | 100 | 0 |
| 5% | 200 | 0 |
Combos earn 10 ÷ the combined chance of every leg, capped at 1,000. Three legs at 50% each (12.5% combined) earn 80. Challenges earn the winner XP like a call on their side's price, capped at 100. Nothing else earns XP. Wrong calls earn 0 and lose none, void markets earn 0, open calls earn nothing until they settle, and backing, fading, following or replying earn nothing. Only being right counts.
Your own numbers live on the Rewards page (also at /rewards, and in your profile menu): what has been tracked, a progress ring to the next rank, the next ranks, the XP you earned on each of the last seven days, and your rebate, referral and streak cards.
Ranks
Your total XP puts you on one of 6 ranks. Wrong calls, lost streaks and cashed-out calls never take XP away, so a rank earned by being right isn't lost by being wrong. The one exception is a correction by an admin (below). Each rank has its own mark, shown on your profile, next to your name and in the header, and tapping it opens your rank card.
XP events and corrections
An admin can run an XP event: a multiplier (2× is the usual, up to 10×) over a set window. While it's on, a lime strip under the beta banner names it and counts down to the end, and the Rewards page says so. The multiplier is applied when a call, combo or challenge settles inside the window, not when it's backed, and the caps still hold (100 for a challenge, 1,000 for a combo). Admins can also correct a person's XP up or down, or pin a rank, when something has gone wrong. Every event, correction and pin is logged with a reason. XP has no cash value and none of this is a prize.
| Rank | XP needed | Fee share tracked |
|---|---|---|
| Rookie | 0 | 0% |
| Regular | 250 | 5% |
| Sharp | 1,000 | 10% |
| Pro | 3,000 | 15% |
| Elite | 8,000 | 20% |
| Legend | 20,000 | 25% |
The fee rebate
Backd charges 1% on every order that fills (see fees). Each rank tracks a share of that fee on your own calls: 5% of it at Regular, up to 25% at Legend. On a $100 call at Pro (15%), the fee is $1.00 and the tracked rebate is $0.15. It is worked out from the fee each of your calls generated, at the rank you held when it filled.
Backd's fee is collected by Polymarket and paid to Backd, so a rebate is money Backd pays out itself, which needs legal sign-off in each country first. Your pages show the rebate accruing from your first call; payouts open once that sign-off is in. There is no prize for a rank.
Streaks
A streak counts the days in a row you've backed a call or a combo. Miss a day and it starts again. Streaks are separate from XP and ranks. A streak doesn't earn XP and losing one doesn't cost any.
Leaderboards
The Leaderboard page ranks by profit or by XP, with right % and calls made as tie-breaks. The XP board rewards lots of hard calls that landed. The profit board is where one big long shot can matter more. The API also offers right % (at least 5 settled) and this week's profit. The top 100 on the XP board get a Top 10, Top 50 or Top 100 badge on their profile. Nobody can delete a bad week. Leaderboards carry no prizes. It's the record, and bragging rights.
